None because gas is a normal part of a baby's development. Also If I were you I would talk to your pediatrician and not the internet for advice.
My oldest daughter was effected by the fast food I was eating from time to time, like burgers. My other daughter was allergic to everything coming from a cow, like meat, milk etc. So I avoided eating those foods for everyone's shake.
It's been a long time since I've been a new mom but if I remember correctly the usual suspects for regular gas production ring true for baby too. So cruciferous vegetables should be avoided.
Foods that make your baby gassy is diary products (cheese, milk, yogurt) and maybe wheat, corn, fish, eggs and peanuts. So maybe a little less of these foods.
Every baby is different. Eat what u want and just wacth you baby for patterns. If you notice the baby gets gassy after you have eaten certain foods then stay away from those foods. For me, spicy foods didn't agree with baby #3 but was just fine with baby #2
